wArsoN F. HAMMOND, or MASHPEE, MASSACHUSETTS-- CRANBERRY-SCREEN.

SPECIFICATION forming part of Letters Patent No. 280,372, dated July 3,1883.

Application filed October 13, 1882. (No model.)

. .To all whom it may concern:

My invention consists of a hopper, platform, screen-grate,discharging-spout, and feeding contrivances, constructed and arranged,as hereinafter described and claimed, to facilitate the screening ofcranberries preparatory to packing them in barrels for market, all ashereinafter described.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is aperspective view of a cranberry screen constructedinaccordance with my i1nprovements. Fig. 2 is a sectional elevationthrough the hopper and screen. Fig. 3 is a detail in side elevation.Fig. 4 is a detail of the jarring device employed to aid in feeding thecranberries, the same being in horizontal section of part of the hopper.

I make a hopper, a, to contain the berries to be screened, the saidhopper having aslanting bottom, I), with a drop-gate, c, below thebottom, forallowing the berries to escape; and over the falling edge ofthe gate is a sliding board, d, to be employed for jarring the hopper tocause the berries to run out in batches, as wanted from time to time.The gate 0 is hinged to the bottom I) at e, and is fastened up to thejar d by a strap or hasp, f, and pin 9 when the hopper is to be closed.Theboard d is fixed in slots 2' of the end boards, j, of the hopper, toslide forward and backward therein, and has a spring, is, to thrust itforward and cause a jar by the cleat Z, attached to it, striking the endof the hopper after the board has been pulled back by the finger of thea tendant applied to the cleat m.

The. screen-grate'n is located in the base or platform 0 of the machine,in advance of the hopper, suitably for the batches of berries to .bespread out over it by the attendant for screening them preparatory toshoving them off through the spout p q into the barrel or otherreceptacle for them. The end section,

q, of the spout-bottom is provided with flange q, and is jointed to therest at s, so that it can be turned over upon the part 1), next tothe-screen, for a stop to prevent berries and other matters fromescaping before they are sufliciently screened, said section beingturned up, as in Fig. 2, when serving to stop the escape, and down, asin Fig. 1, to allow the escape of the berries.

For enabling thehopper to be taken off of the platform to be filled, itis detachably connected thereto by means of the grooved cleats t,attached to the edges of the platform, and cleats u, attached to theends of the hopper, enabling the hopper to be readily connected anddisconnected by sliding out and in the grooves of cleats t from the backof the platform.

Theplatform 0 is designed to be set up on any suitable support at theback, with the spout end resting on the top of the barrel, box, or otherreceptacle for the berries, so that they will discharge from the spoutinto said receptacle.

The hopper hascleats w, attached to the upper edges of the ends j, forhandles, by which to lift it when removing it from the platform to befilled and replacing it again, and when so filled and in position thestrap or hasp f is lifted from pin g and the hinged bottom 0 opened,whereupon the jar cl may be operated, as above described, to causeamoderate amount of berries to fall from the hopper at each movement ofthe jar (Z upon the screen a, to be assorted and discharged.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination, with the platform 0 and grate a, of the hopper a,provided with dropgate 0 and the j arrin g-board (Z, substantially asdescribed.

2. The grate a, provided with the spoutp g, the part q being providedwith the flange q and hinged to the part p,'andadapted to be turned overupon said part p to form a stop, substantially as and for the purposeset forth.

3. The combination of hopper 0, having drop-gate c and jarring-board d,with the platform 0 and grate u, said hopper and platform beingdetachably connected together, substantially as described.

4. The sliding board (I, having cleats Z and I jarring-boardsubstantially as herein shown an and spring 70, in combination withhopper a and described. and grate n, substantially as described. u

5. The combination with the hopper a, hav- 5 ing a slanting bottom b,and the jarring-board Vitnesses:
